Quiz: Will You Have Twins?

Twins are on TV, in celeb magazines, at the playground--just about everywhere we look, and for good reason. According to 2009 data from Centers for Disease Control and Prevention, there are more twins born today than ever before. (One in 30 births in 2009 were twins, compared with 1 in 53 in 1980.) Multiples are multiplying because more and more women are undergoing fertility treatments, according to Jennifer Wu, M.D., an ob-gyn at Lenox Hill Hospital in New York City. But there are several factors that increase your odds of conceiving twins naturally, too, including your family history, weight, height, and even your dietary preferences. Take our quiz to help determine your odds of seeing double.
